with any no heat complaint the first thing to check is going to be the coolant level. then make sure the vehicle is reaching proper operating temperature and that the thermostat is not stuck open or anything. from there check and see if both of the heater hoses are getting hot, those are the coolant hoses going into the firewall towards the passenger side of the vehicle. if one is hot and the other is cold that means you have a restricted heater core. you can try to backflush the heater core by taking a garden hose and connecting through the outlet side of the heater core and spraying out the inlet side. if that does not work you will have to replace the heater core. hope that helps.
